Flory-Krigbaum potential

While the Flory-Krigbaum potential is a qualitatively reasonable form for polymers in a good solvent, it completely misrepresents the shape of the potential of mean force near the Flory temperature. The potential of mean force is positive and repulsive for small values of the center-of-mass separation, just as it was for the overlap of two subchains. For the overall excluded volume to vanish, the potential of mean force must be negative for small degrees of overlap. The Flory compensation temperature is a balance... [Pg.52]

While the Flory-Krigbaum potential is not exact, it is in closed form and enabled them to evaluate the integral and obtain ... [Pg.17]

The theory of the second osmotic virial coefficient in moderate salt solutions was developed in detail by Orofino and Flory. ° An extension of the Flory-Krigbaum approach was also developed. The chemical potential of the solvent in a nonionic solution was expressed as ... [Pg.124]

The approach of Flory and Krigbaum was to consider an excess (E) chemical potential that exists arising from the non-ideality of the polymer solution. Then ... [Pg.84]

An approximate potential of mean force for two polymer coils in a good solvent was developed by Flory and Krigbaum. It is based on the same... [Pg.51]
